2925 WETMORE AVE CAFE UU 2023-10-25

Drew Martin From: Drew Martin Sent: Thursday, May 25, 2023 3:01 PM To: CJ Williams Subject: City of Everett Permit Services; 2925 Wetmore Avenue (52303-001) - Third Building Review Good afternoon, CJ. This email recaps our conversation regarding documentation that needs to be submitted for review. As discussed, a revised engineering detail is also required. Revised documents should be uploaded to the City of Everett permitting application. Please address the following: 1. Submit revised construction drawings including structural details. 2. The FOR has not addressed the design of the sign using the proper wind loading procedure as stated in previous comments. Additional action is not being required for this comment; this issue is being stated for posterity. 3. The detail specifies a %" rod with an embedment in the masonry of 2". The connection should also specify the HIT -SC sieve sleeve. The embedment depth should be noted to not include the stucco thickness. 4. The drawings should specify continuous special inspection to be performed for the anchor installation by a qualified special inspector per IBC Chapter 17. 5. The groove weld between the sign plates and mounting plate does not appear to comply with the prequalified weld connections of AISC 360. Specifically, the end -butting of the two plates is anticipated to yield only a partial groove weld of inadequate thickness and will experience burn -out the edge of the mounted plates. The weld should be revised. It is recommended that the mounting plate extend past the sign plates. Special inspection should be specified for the welding of the steel connections per IBC Chapter 17. 6. Continuing with the previous comment, the proposed weld has minimal flexural capacity. The heavy weight of the sign, eccentric center -of -gravity, and cantilever length of the sign plates with result in flexural loading in the plate and weld. The welds are prone to sudden brittle failure. Stiffener plates should be provided between the sign and mount plates to eliminate flexure in the welds. Alternatively, calculations substantiating the flexural capacity of the plates and welds should be submitted for review. The effective depth of the welds for strength should be limited based on the appropriate prequalified weld per AISC 360; the prequalified weld used be specified in the detail and calculations for reference.
